I used this playpen at work for a year. Purchased when my daughter was almost a year old. I had to take it in and out of my car everyday at work and I was worried that it wouldn't hold up due to it being hollow plastic. I was pleasantly surprised! It held up so well that I will be able to use it again for the next baby. My daughter is now two and knows how to stack things so she can climb out and she's tall. However she has never been able to figure out how to unlock the gate. All the toys on the toy panel still work and have held up despite my daughter being rough with them. None of the connector pegs have come off during transport. I really worried they would pop off since they weren't solid and were jostled in my car all the time!
